I just setup a new piaware feeder. I’m running a pi4 with 2 nooelec nano 3 rtl-sdr’s. I’m running 1090 & 978, both with diy 1/4 wave ground plane antennas. The antennas are in a 3rd story attic. I used a nanovna to tune the antennas.
I get a reliable 150nm, with sprinkles of 200nm+. Still tweaking the system, but pretty happy with how its performing so far.
